Game locks up after a short whil

[KristofferAG]

THe C++ issues I had were fixed, but now, the game locks up after a short time. It seem time-based, at least. It differs how long it takes before it locks up, it can be during the comic, right after the comic, before I can finish writing my nickname on the diploma, or during the loading screen. It all seems very random. One time, the music lagged and looped itself as well, but for the most time, the screen just locks up.

Does anyone have any solutions to this issue?
